Description

Technical Field

[0001] The invention relates to the technical field of prefabricated wall panels, and in particular to a prefabricated building wall panel. Background Art

[0002] In traditional building construction, walls are mostly constructed by brickwork. The emergence of prefabricated wall panels has increased the speed of construction, so in existing construction, prefabricated wall panels are mostly used for non-load-bearing walls.

[0003] In the existing construction, the prefabricated wall panels still use concrete materials or concrete foam materials, and are relatively large in size. Since they are not load-bearing structures, the structural strength of this type of prefabricated wall panels is low, and there is a problem of breakage during transportation. During installation, due to the problem of volume and weight, the installation is also inconvenient. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses an assembled building wall panel, including a wall panel unit and a column for supporting and fixing the wall panel unit. The upper and lower ends of the column are fixed to the ground and the ceiling, and the wall panel unit is fixedly connected to the column, so that the wall panel can be miniaturized, which is convenient for installation and transportation.

[0005] The wall panel unit includes a horizontal panel and a vertical panel, and the horizontal panel and the vertical panel form a rectangular parallelepiped frame, and a foam material is arranged inside the frame. By arranging the foam material, the functions of heat insulation and sound insulation are realized.

[0006] The ends of the horizontal plates are bent and provided with through holes, and holes are also provided at the positions of the vertical plates that coincide with the through holes, leaving riveting positions. Connecting parts are passed through the holes to achieve fixed connection between the horizontal plates and the vertical plates, preferably by riveting, because the wall panels do not need to be disassembled after production, and riveting can ensure long-term stability of the connection.

[0007] The front and rear sides of the frame are both provided with plates, and a number of protrusions are punched on the plates, and through holes are set at the ends of the protrusions. A connecting plate is punched and folded on the horizontal plate, and a first hole is set on the connecting plate. The first hole and the through hole of the protrusion at the corresponding position are overlapped, and a riveting position is reserved. Similarly, the plate and the horizontal plate are fixed by riveting, and protrusions are set, and the protrusions are connected to the inside of the frame. After riveting, the height of the riveted structure is lower than the surface height of the plate. At the same time, the horizontal plate and the plate are both stamped to obtain the riveted support structure, and there is no need to set up additional components for riveting, which ensures the stability of the connection. Furthermore, foaming is performed inside the frame, and the foaming agent can be injected from the holes generated after the connecting plate is punched.

[0008] Preferably, the side wall of the vertical plate is riveted with a connecting profile, a first pipe is embedded in the connecting profile, and the column is composed of a supporting profile and a second pipe, the first pipe and the second pipe have the same structure and are both provided with countersunk holes. That is, the connecting profile is in contact with the supporting profile, and the first pipe and the second pipe are ensured to overlap, at which time a screw can be used to penetrate the first pipe and the second pipe to achieve a fixed connection between the two.

[0009] Preferably, the cross-sectional profile of the supporting profile is L-shaped, and a plurality of second holes are arranged at equal distances on the side wall of the supporting profile. In the L-shaped structure, after the connecting profile and the supporting profile are fixedly connected, the cross-sectional profiles of the two constitute a rectangle. The purpose of providing the second holes is to be used for the fixed connection between the supporting profile and the adjacent components. If two supporting profiles are arranged side by side, a screw and a nut can be used to achieve the fixed connection between the two.

[0010] Preferably, a coating is attached to the surface of the plate to cover the raised structure and improve the appearance of the front plate unit.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The volume is relatively small, and the foam material is set inside, so that the wall panel unit has the ability of heat insulation and sound insulation. At the same time, the weight is relatively small, which is convenient for quick installation.

[0013] 2. The components on the wall panel unit are connected by stamping and riveting. Due to the stable connection effect of riveting, the wall panel unit connection is stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] like Figures 1 to 5 As shown, a prefabricated building wall panel includes a wall panel unit 1 and a column 2 for supporting and fixing the wall panel unit 1. The wall panel unit 1 is provided with multiple pieces. Compared with the existing whole wall panel, this solution is more conducive to transportation and installation. The upper and lower ends of the column 2 are respectively fixedly connected to the ceiling and the ground, and then the wall panel unit 1 is fixedly connected to the column 2 in turn.

[0024] The wall panel unit 1 includes a horizontal panel 13 and a vertical panel 14, and the horizontal panel 13 and the vertical panel 14 form a rectangular frame, and a foaming material is arranged inside the frame. The foaming material is arranged so that the wall panel unit 1 has the ability of sound insulation and heat preservation.

[0025] The end of the horizontal plate 13 is bent and provided with a through hole. At the same time, a hole is also provided on the vertical plate 14 at a position overlapping with the through hole. Riveting is used to achieve a fixed connection between the horizontal plate 13 and the vertical plate 14. Furthermore, the bending angle of the end of the horizontal plate 13 is 90°, and the bent portion and the vertical plate 14 are fitted together.

[0026] The front and rear sides of the frame are provided with plates 12, making the frame a relatively closed component. Several protrusions 19 are punched on the plate 12, and through holes are set at the ends of the protrusions 19. A connecting plate 17 is punched and folded on the horizontal plate 13, and a first hole 18 is set on the connecting plate 17. The first hole 18 at the corresponding position and the through hole of the protrusion 19 are overlapped. The plate 12 and the horizontal plate 13 are fixedly connected by riveting. The protrusion 19 is set, and the protrusion is set toward the frame. The rivet is located inside the protrusion. This setting makes the surface of the plate 12 flat. At the same time, the structure for riveting between the plate 12 and the horizontal plate 13 is formed by stamping, and no other components need to be added. Furthermore, when the foaming agent is injected into the frame, it can be injected through the hole formed by punching the connecting plate 17.

[0027] The side wall of the vertical plate 14 is riveted with a connecting profile 16, and a first pipe 15 is embedded in the connecting profile 16. The first pipe 15 can be fixedly connected to the connecting profile 16 by interference fit or welding. The column 2 is composed of a supporting profile 21 and a second pipe 22, and the connection method of the two is consistent with the first connecting pipe 15 and the connecting profile 16. The first pipe 15 and the second pipe 22 have the same structure and are both provided with countersunk holes. When the wall panel unit 1 and the column 2 are assembled, the first pipe 15 and the second pipe 22 are aligned, and then the screw is inserted and fixed with nuts at both ends to achieve the fixation between the wall panel unit 1 and the column 2, while ensuring the beauty, and the nuts are located in the countersunk holes.

[0028] The cross-sectional profile of the supporting profile 21 is L-shaped. After the supporting profile 21 and the connecting profile 16 are matched, the cross-sectional profile is rectangular, and a number of second holes 23 are arranged at equal distances on the side wall of the supporting profile 21. The second holes 23 are used to connect the supporting profile 21 and adjacent components. For example, if two profiles 21 are side by side, bolts and nuts can be used to fix the two through the second holes 23.

[0029] The surface of the plate 12 is attached with a coating 11. The pits produced by punching the protrusions 19 are covered. If necessary, putty powder can be filled in the pits, and then the coating 11 is attached.

[0030] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
